And if you could.... (Sorry JST.. Not trying to hijack, just wonder if people can answer both in one....)

Would a 300TDi airbox be good enough for a 3.9 V8? (Part number ESR2102)

(Ralph.. Trash if I've been a naughty boy..)

cheers ralph, will give it a go and see what happens. same capacity but one has an intercooler and higher (?) pressure turbo so isint the air compressed more so therefore more air goes in to the cylinder? therefore it needs to draw more air???

a turbo 2.5 certainly draws more air than a N/A

IIRC the Defender 200Tdi & TD air filter elements are almost the same diameter & length, so I would expect the through flow of air into the engine to be similar.

Try it & can't see why it shouldn't work, both engines would draw the same amount of air as they are the same cubic capacity.

Neil, as above try it.

The amount of air drawn is higher in a TDI because it is running at higher boost.

A TDI at 15 psi versus a TD at 6 psi draws (15 + 14.7) / (6 + 14.7) = 43% more air. Actually a little less due to losses into the cylinders, but that is the ballpark.
